Here is what the Rainbow Cloud does in LEGO Fortnite, which you will find floating at the end of a rainbow.
There are plenty of different items you will come across in LEGO Fortnite, most of which will give you loot.
One of the objects you will come across are clouds with rainbows in LEGO Fortnite, which you will find at the end of a rainbow in the sky.
How to Get onto the Rainbow Cloud in LEGO Fortnite?
You will see the cloud hovering in the sky, which will have some LEGO characters on top, which will be in colours of the rainbow. In order to reach the top of the cloud, you will need to build some stairs.
In order to make stairs, you will need some Wood. These can be found by chopping down normal trees with an Axe in the standard biome.
Go into build mode and navigate to the “Building Parts” section. In this menu, you will find “Stairs” as one of the options.
Under the Stairs section, you can choose either Rustic Stairs 01 or Rustic Stairs 02 to build up to the cloud. Both of these options take only 2 Wood, so it should be easy to make.
Once you are on the cloud, you will be see that these LEGO characters will be dancing. All you need to do is dance with the LEGO characters, which will drop loot.
You can perform any emote in order for this to work.
After you have danced with the LEGO, they will disappear one by one and the cloud will disappear shortly after as well.
The Rainbow Clouds spawn randomly, but you will be able to hear a sound when they are near and if you see a rainbow in the sky, you can follow it to the cloud that should be at the end of it.
